Pseudoephedrine belongs to a group of medications called decongestants. It is used to temporarily relieve symptoms of nasal or sinus congestion that occur with allergies, sinusitis, ear infections, and the common cold. Pseudoephedrine works by causing the blood vessels in the sinuses to tighten, decreasing the swelling of the sinuses and making it easier to breathe.
